In the process of making bracket feet for a small spice cabinet, on my table saw, I am having trouble with the results. I used the online calculator for the blade tilt and fence angle. The problem is the apex is in the wrong direction. I entered minus 0.025 for the offset, but the calculator won’t take a negative number and I don’t know how to shift the apex to the left. If I change the fence angle from 71 degrees to 21 degrees, my fence will be right to left but the blade is tilted left so the fence should be left to right. It looks to me like the apex (the left line) is the center of the circle and I have it set at the center of the ellipse. Any comments?

Maybe you could post some photos or a drawing. I think most folks (like me) are going to have a hard time visualizing what you’re describing.

I hope these got uploaded. Sure hope somebody can help us. Markum I think your offset should be .250. I think we’re working on the same spice cabinet? From American Woodworker Feb 1994 #36?

It looks like if you ran the stock the opposite direction you would have the arch you want,if that doesn’t work try hot glueing a strip to one side of the stock to raise it up on one edge.

the template id is width of cove ( 1 5/8”) od is height of foot (2 5/8 “)

fence angle is 71 degrees

You are right Jim. The blank is rougher than the first cut. I had to move the fence to register the 1/4 ” margin on the left instead of right and the start/ stop points are not the same. I’m making a pine prototype and a cherry finished spice cabinet. So far I’ve made all the mistakes on the proto. Thanks for your help

Update. I switched to a 7 1/4” – 40 tooth blade. New settings are fence angle 67 degrees, blade tilt 28 degrees. I used a slightly wider blank. This time I set the fence so that just the left side just touched the upcoming tooth and set the angle. On the previous try I set the fence so both the upcoming and downward teeth just touched the blank. The fence angle was always off. Here is the result. I haven’t used a scraper yet this is right off the saw table.
